4 Description of the product

4.1 General description

POWER HT + floor-standing condensing gas boilers have the following

characteristics:

Low pollutant emissions

High efficiency heating

Electronic control panel

Flue gas discharge by a forced flue, chimney or bi-flow type connection.

Perfectly suitable for cascade systems with several boilers.

4.2 Operating principle

4.2.1 Circulation pump

Note

The benchmark for the most efficient circulators is EEI ≤ 0.20.

4.2.2 Gas/air setting

The casing fitted to the boiler is also used as an air box. Air is drawn in by

the fan and gas injected into the Venturi by the fan intake. The fan speed

is modulated according to the settings, the heat demand and the actual

temperatures measured by the temperature sensors. The gas and air are

mixed in the Venturi. The gas/air ratio command function accurately ad

justs the quantities of gas and air required. This provides optimum com

bustion over the entire output range. The gas/air mixture is sent to the

burner, located upstream of the heat exchanger.

4.2.3 Low-loss header (accessory)

The low-loss header is used to prevent interaction between the dynamic

pressures within the boiler and the heating circuits. The low-loss header

considerably reduces the variations in pressure and flow rate caused by

the use of several circulating pumps in an installation and is used to man

age flows in the installation and to control temperatures.

header kit

4.2.4 System in cascade

The boiler is ideally suited for a cascade system configuration. Use a boil

er/cascade connection kit to connect boilers in cascade.

4.2.5 Settings and safety devices

Note

The settings and safety devices are only operational if the boiler is

powered up.

Tab.10 Description of the safety devices

Device Description

Safety thermostats The safety thermostats suspend the supply of gas to the burner if the water in the pri

mary circuit overheats. To resume normal operation of the boiler, eliminate the cause of

this interruption.

Caution

The safety thermostats must in no circumstances be switched off or

disconnected.

NTC flue gas sensor The control panel blocks the gas supply to the burner in the event of overheating. To

resume normal operation of the boiler, switch off the boiler and switch it back on again

with the ON/OFF switch.

Flame detector by ionisation The boiler is put into safety shut-down in the event of gas shortage or incomplete inter

ignition on the burner.

Hydraulic pressure switch Thanks to this device, the burner can only operate if the system pressure is higher than

0.5 bar (0.05 MPa).

When the pressure switch detects a pressure lower than 0.8 bar (0.08 MPa), a warning

message is displayed, without stopping the circulating pump.

Post-circulating pump After the burner stops, depending on the room thermostat setting and if in heating

mode, the circulating pump runs for a further 3 minutes.

Frost protection device When the flow temperature is lower than 5°C, the burner starts up and runs until the

flow temperature reaches 15°C. This device runs under the following conditions:

The boiler is switched on

The gas supply is working

The pressure in the system is higher than 0.5 bar (0,05 MPa)

Anti-blocking of the pump If there are no heating or domestic hot water requirements for 24 consecutive hours, the

pumps start up automatically and run for 10 seconds.

The pumps connected directly to the appliance's terminal blocks are started up every

Friday at 10:00 a.m. and run for 30 seconds.

Anticipatory start-up of the circulat

ing pumps

In heating mode only, the appliance can start up the circulating pumps before burner ig

nition. The duration and activation of anticipatory start-up depends on the conditions of

installation and the operating temperatures. The duration of anticipatory start-up of the

circulating pumps therefore varies from a few seconds to several minutes.
